Store Issues and Out of Date

So I have a few issues with the WIX store as an e-commerce platform.

1) We could do with more layers on the subpages, the Main page and a Subpage is not enough for the majority of applications. This results in having to put hyperlinks on other pages to hidden pages (so these don't appear un-sorted in the menu bar) this brings me onto point 2.

2) As we cannot correctly create sub-pages, we then have to build our own breadcrumbs for every sub-page these, therefore, cannot be the dynamic pages meaning we soon hit the 100-page limit.

3) Sorting by Product Specifics is an issue, If I want to add the ability to sort by manufacturers, I either have to do it as a collection, which gets messy or as a product option (this is how I prefer to do it) however this then means that the user has to select the manufacturer as an option. Can we not have the specifics of an item that can then be used within the filters without the need to select them as options?

4) In-store share features are out of date and should be customisable, these colours are fixed, and cannot be changed as well as things like google plus don't exist any more
